    An improved test device, based on the light emitting device (LED) presented in the following article (L. Pavesi, R. Guardini, P. Bellutti, Thin Solid Films 297 (1997) 272) is reported. The whole processing of the diode is CMOS compatible and the porous Si (PS) formation is at the end of the run. The idea of the LED is to exploit the doping selectivity of the silicon anodization by forming n+ -type doped crystalline Si stripes floating over the porous silicon layer. Electrical injectionis through the n+ stripes into the PS, i.e. through a SI/PS heterojunction. Here, the electrical and optical properties of the electochemically oxidized LED are characterized. Anodic oxidation improves the LED performance both in terms of stability (more than 8 days under CW excitation) and efficiency (a factor 3 or higher with respect to the as-grown LED

    46. Haemaphysalis erinacei Pavesi, 1884, but see note below. A Palearctic species, all of whose parasitic stages have been found on Carnivora: Canidae, Erinaceomorpha: Erinaceidae, and Rodentia: Muridae. Adults and nymphs have been collected from Lagomorpha: Ochotonidae; adult ticks alone have been detected on Artiodactyla: Bovidae, Carnivora: Felidae, Hyaenidae and Mustelidae, and Lagomorpha: Leporidae, with rare records from Coraciiformes: Meropidae, and Testudines: Testudinidae; immature stages have been recovered from Rodentia (several families), Chiroptera: Vespertilionidae, Caprimulgiformes: Apodidae, and Passeriformes: Motacillidae (Maslennikova et al. 1964, Guglielmone et al. 2014; Guglielmone & Robbins 2018). Haemaphysali s erinacei is a rare parasite of humans. M: Pavesi (1884) F: Neumann (1905), under the name Haemaphysalis numidiana, a synonym of Haemaphysalis erinacei; see note below N: Pospelova-Shtrom (1940), under the name Haemaphysalis numidiana turanica, another synonym of Haemaphysalis erinacei L: Pospelova-Shtrom (1940), under the name Haemaphysalis numidiana turanica Redescriptions M: Feldman-Muhsam (1951), under the name Haemaphysalis erinacei (see note below), Hoogstraal (1955a), Filippova et al.

L: Hoogstraal (1955a), Filippova (1997), Estrada-Peña et al. (2017) Note: Haemaphysalis erinacei Pavesi, 1884 has priority over Haemaphysalis erinacei Feldman-Musham, 1951, which is a synonym of Haemaphysalis erinacei Pavesi, 1884. The female of Haemaphysalis erinacei described by Pavesi (1884) does not belong to Haemaphysalis, as explained in Feldman-Muhsam (1953); therefore, translations of the description of the female of Haemaphysalis erinacei by Pavesi (1884), as in Neumann (1897), are not included in the above lists. There are also several redescriptions of subspecies of Haemaphysalis erinacei that are not included in our lists. Morphological and molecular differences among populations, as described in Filippova et al. (1993), Filippova (1997) and Hornok et al. (2016c), are strong indicators that more than one taxon may be represented under the name Haemaphysalis erinacei. See also Haemaphysalis cooleyi and Haemaphysalis pedetes for their confusion with Haemaphysalis erinacei.Published as part of Guglielmone, Alberto A., Petney, Trevor N. & Robbins, Richard G., 2020, Ixodidae (Acari: Ixodoidea): descriptions and redescriptions of all known species from 1758 to December 31, 2019, pp. 1-322 in Zootaxa 4871 (1) on page 162, DOI: 10.11646/zootaxa.4871.1.1, http://zenodo.org/record/442334
